Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a composite high-temperature resistant elastomer insulated rubber-sheathed cable. Background Technology

[0002] A cable is a conductor made of one or more mutually insulated conductors and an outer insulating protective layer. Cables generally consist of three parts: conductor, insulation layer, and protective layer. There are usually two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy, while control cables are mainly used for measurement, protection, and control lines. Cables have the characteristics of being internally energized and externally insulated.

[0003] The published patent document with announcement number CN217113925U discloses a flexible insulated cable. This published patent document uses tin-plated copper conductors to prevent copper from being oxidized in high-temperature environments. It uses calcined mica tape as insulation material, which can significantly improve the fire resistance temperature rating of the cable and reduce the fluorine content. However, the published patent document cannot compress, buffer, and rebound when subjected to compression, and cannot provide good anti-compression protection for the copper conductors, making the cable easily damaged after compression. Utility Model Content

[0004] The purpose of this invention is to provide a composite high-temperature resistant elastomer insulated rubber-sheathed cable, which solves the problems mentioned in the background art.

[0005] This application provides a composite high-temperature resistant elastomer insulated rubber-sheathed cable, including a rubber outer jacket, a matching inner silicone core inside the rubber outer jacket, a circular hole in the center of the inner silicone core, and several buffer holes on the inner silicone core. Several copper wires are arranged inside the circular hole. The several buffer holes are distributed in a circular array at equal intervals with the axial direction of the inner silicone core as the center. A heat insulation sleeve is provided between the rubber outer jacket and the inner silicone core.

[0006] By adopting the above technical solution, the buffer hole opened on the inner silicone core can play a compression buffer when the cable is squeezed, with a high elasticity effect, preventing the copper conductor from being squeezed, and the heat insulation sleeve between the rubber jacket and the inner silicone core gives the cable high temperature resistance.

[0007] Optionally, a reinforcing layer is provided between the heat insulation sleeve and the rubber outer sleeve, and the heat insulation sleeve is made of fiberglass.

[0008] By adopting the above technical solution, the heat insulation sleeve made of glass fiber gives the cable high temperature resistance, and the reinforcing layer between the heat insulation sleeve and the rubber jacket increases the strength of the cable.

[0009] Optionally, the reinforcing sleeve is in the shape of a wire mesh.

[0010] By adopting the above technical solution, the reinforcing sleeve in the shape of a wire braided mesh increases the tensile strength of the cable, thereby increasing the cable's toughness and strength.

[0011] Optionally, the interior of the circular hole is filled with cross-linked polyethylene filler, which separates the plurality of copper wires.

[0012] By adopting the above technical solution, cross-linked polyethylene filler separates the individual copper conductors, giving the cable good insulation properties.

[0013] Optionally, the outer wall of the rubber jacket is provided with anti-slip texture.

[0014] By adopting the above technical solution, the anti-slip texture on the outer wall of the rubber jacket increases the anti-slip performance of the cable.

[0015] Optionally, the copper conductor is fitted with a matching conductor rubber sleeve.

[0016] By adopting the above technical solution, the conductor rubber sleeve prevents the copper conductor from directly contacting and adhering to the cross-linked polyethylene filler.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application, through a rubber jacket, an inner silicone core, buffer holes, round holes, and cross-linked polyethylene filler, can not only play a compression buffering role when the cable is squeezed, giving the cable a high elasticity effect and providing anti-compression protection for the copper conductors, but also separate the individual copper conductors, giving the cable good insulation.

[0018] The technical solution of this application enables the cable to have high temperature resistance by setting a heat insulation sleeve, and the reinforcing layer between the heat insulation sleeve and the rubber jacket is in the shape of a wire braided mesh, which increases the tensile strength of the cable and thus increases the toughness and strength of the cable.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1-2 This utility model provides a composite high-temperature resistant elastomer insulated rubber-sheathed cable, including a rubber outer jacket 1, a matching inner silicone core 2 inside the rubber outer jacket 1, a circular hole 3 in the middle of the inner silicone core 2, and a plurality of buffer holes 7 on the inner silicone core 2, a plurality of copper wires 4 inside the circular hole 3, and the plurality of buffer holes 7 are distributed in a ring array at equal intervals with the axial direction of the inner silicone core 2 as the center, and a heat insulation sleeve 5 is provided between the rubber outer jacket 1 and the inner silicone core 2. In this technical solution, the buffer hole 7 opened on the inner silicone core 2 can play a compression buffer when the cable is squeezed, with a high elasticity effect, preventing the copper conductor 4 from being squeezed, and playing an anti-compression protection role for the copper conductor 4. In addition, the heat insulation sleeve 5 between the rubber jacket 1 and the inner silicone core 2 plays a good heat insulation role, giving the cable high temperature resistance.

[0023] In some technical solutions, such as Figure 2 As shown, a reinforcing sleeve 8 is provided between the heat insulation sleeve 5 and the rubber outer sleeve 1, and the heat insulation sleeve 5 is made of fiberglass.

[0024] In use, the fiberglass insulation sleeve 5 enables the cable to withstand high temperatures, and the reinforcing layer 8 between the insulation sleeve 5 and the rubber jacket 1 increases the strength of the cable.

[0025] In some technical solutions, such as Figures 2-3 As shown, the reinforcing layer 8 is in the shape of a woven wire mesh.

[0026] In use, the reinforcing sleeve 8, which is in the shape of a wire mesh, increases the tensile strength of the cable, thereby increasing the cable's toughness.

[0027] In some technical solutions, such as Figure 2 As shown, the interior of the circular hole 3 is filled with cross-linked polyethylene filler 9, which separates several copper wires 4.

[0028] In use, the individual copper conductors 4 are separated by cross-linked polyethylene filler 9, giving the cable good insulation.

[0029] In some technical solutions, such as Figure 1 As shown, the outer wall of the rubber jacket 1 is provided with anti-slip texture 6.

[0030] When in use, the anti-slip texture 6 on the outer wall of the rubber jacket 1 increases the cable's anti-slip performance.

[0031] In some technical solutions, such as Figure 2 As shown, a matching wire rubber sleeve 10 is fitted onto the copper wire 4.

[0032] During use, the wire rubber sleeve 10 prevents the copper wire 4 from directly contacting and sticking to the cross-linked polyethylene filler 9.

[0033] Working principle: During use, when the cable is compressed, the buffer holes 7 on the inner silicone core 2 can act as a compression buffer, giving the cable a high elasticity effect and preventing the copper conductors 4 from being squeezed, thus providing anti-compression protection for the copper conductors 4. In addition, the heat insulation sleeve 5 between the rubber jacket 1 and the inner silicone core 2 provides a good heat insulation effect, giving the cable high temperature resistance. The reinforcing layer 8, which is in the shape of a wire braided mesh, increases the tensile strength of the cable, thereby increasing the cable's toughness and strength. The cross-linked polyethylene filler 9 separates the individual copper conductors 4, giving the cable good insulation.
